Solidago plant named &#39;dansolwind&#39;

ABSTRACT

A new and distinct  Solidago  plant named ‘Dansolwind’ particularly characterized by having a plant height of 70-75 cm., small yellow inflorescences, green leaves, a rapid growth cycle and an even growth rate.

BOTANICAL DESCRIPTION

Solidago sp.

VARIETY DENOMINATION ‘Dansolwind’ BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of thegoldenrod plant, botanically known as Solidago sp., and hereinafterreferred to by the cultivar name ‘Dansolwind’.

Solidago, of the sunflower family, Asteraceae, consists of approximately100 species of goldenrod plants found in North America, most of whichare geographically located in the East. Goldenrods are perennial plantsthat commonly grow along stream banks, ditches, roadsides and otherareas where the soil is moist and rich.

The new Solidago cultivar is a product of a planned breeding programconducted by the inventor, Gabriel Danziger, in Moshav Mishmar Hashiva,Israel. The objective of the breeding program was to develop a newSolidago variety with a small yellow inflorescence, green leaves, arapid growth cycle, and an even growth rate.

The new Solidago cultivar originated from a cross made by a plannedbreeding program discovered by the inventor in 2000 in Moshav MishmarHashiva, Israel. The female parent is designated as ‘1-Y-1’(unpatented). The male parent is unknown. The new Solidago cultivar‘Dansolwind’ was selected by the inventor as a flowering plant withinthe progeny of the stated cross in a controlled environment in MoshavMishmar Hashiva, Israel.

Asexual reproduction of the new Solidago cultivar by leaf cuttings wasfirst performed in October, 2001, in Moshav Mishmar Hashiva, Israel, andhas demonstrated that the combination of characteristics as hereindisclosed for the new Solidago cultivar are firmly fixed and retainedthrough successive generations of asexual reproduction. The new cultivarreproduces true to type.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe unique characteristics of ‘Dansolwind’ which in combinationdistinguish this Solidago as a new and distinct cultivar:

1. Small yellow inflorescences;

2. 70-75 cm in height;

3. Green leaves;

4. Rapid growth cycle; and

5. Even growth pace.

Plants of ‘Dansolwind’ differ from the plants of the female parent,‘1-Y-1’ (unpatented) primarily in branch and inflorescence strength.‘Dansolwind’ has sturdier branches and denser inflorescences than themother plant.

Of the many commercial cultivars known to the present inventor, the mostsimilar in comparison to ‘Dansolwind’ is the Solidago cultivar ‘Tara’(unpatented). Both cultivars have small yellow inflorescences. However,the inflorescences of ‘Tara’ are a lighter yellow color, most similar toyellow group, RHS 7A, whereas the inflorescences of ‘Dansolwind’ aremost similar to yellow group, RHS 13A.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the overall appearanceof the new Solidago cultivar ‘Dansolwind’ showing the colors as true asis reasonably possible with colored reproductions of this type. Color inthe photographs may differ slightly from the color value cited in thedetailed botanical description which accurately describe the color of‘Dansolwind’.

The first photograph shows a side view perspective of a typical, potted‘Dansolwind’ at the age of 10 weeks. The second photograph shows aclose-up of a yellow inflorescence of ‘Dansolwind’ at the age of 10weeks.

DETAILED BOTANICAL DESCRIPTION

The new Solidago cultivar ‘Dansolwind’ has not been observed under allpossible environmental conditions. The phenotype of the new cultivar mayvary significantly with variations in environment such as temperature,light intensity, and day length without any change in the genotype ofthe plant.

The aforementioned photographs, together with the followingobservations, measurements and values describe the new Solidago cultivaras grown in the field in Moshav Mishmar Hashiva, Israel, underconditions which closely approximate those generally used in commercialpractice. The photographs and descriptions were taken during Septemberof 2004, when the outdoor day temperature averaged 30° C. and theoutdoor night temperature averaged 24° C. The plant was grown withfertilization N:P205:K20 in the ratio of 5:3:8. The age of plantsdescribed is 10 weeks.

Color references are made to The Royal Horticultural Society ColourChart (RHS), 2001, except where general colors of ordinary significanceare used. Color values were taken under daylight conditions atapproximately 12:00 p.m. in Moshav Mishmar Hashiva, Israel.
